---|---|
What is anatomy? | the study of the structures of body parts, their forms, and organization |
What is physiology? | the study of the functions of body parts, what they do, and how they do it |
Structure equals | function |
List the levels of organization. | subatomic particles, atoms, molecules, macromolecules, organelles, cells, tissue, organs, organ systems, and organism |
What is metabolism? | all chemical reactions in an organism that support life |
What are the characteristics of life? | movement, responsiveness, growth, reproduction, respiration, digestion, absorption, circulation, assimilation, and excretion. |
Whar are the requirements of all organisms to maintain life? | water, food, oxygen, heat, and pressure |
What is homeostasis? | the body's maintenance of a stable internal environment |
How does the body maintain homeostasis? | homeostatic mechanisms |
What are the parts of a homeostatic mechanism? | receptor, control center, and effector |
What is a negative feedback mechanism? | when your body moves conditions back towards the set point and then stop |
Give an example of a negative feedback. | when your body moves away from 98.6 F, your body gets it back to that temperature, then the feedback stops |
What is a positive feedback mechanism? | when your body moves conditions away from the set point |
Give an example of a positive feedback | child labor, and blood clotting |
